Zhu, Chenyang; Garcia, Heriberto; Kaplan, Anna; Schinault, Matthew; Handegard, Nils Olav; Godø, Olav Rune; Huang, Wei; Ratilal, Purnima (Journal article; Peer reviewed, 2018)Multiple mechanized ocean vessels, including both surface ships and submerged vehicles, can be simultaneously monitored over instantaneous continental-shelf scale regions >10,000 km 2 via passive ocean acoustic waveguide ... -
The effect of attenuation from fish on passive detection of sound sources in ocean waveguide environments
Duane, Daniel; Zhu, Chenyang; Piavsky, Felix; Godø, Olav Rune; Makris, Nicholas C. (Peer reviewed; Journal article, 2021)Attenuation from fish can reduce the intensity of acoustic signals and significantly decrease detection range for long-range passive sensing of manmade vehicles, geophysical phenomena, and vocalizing marine life. The effect ...
